Title: Flat knitting machine
IPC: D04B15/36
Filed: 1974-03-13
Abstract: 1452797 Knitting machines H STOLL G STOLL E STOLL E STOLL J STOLL A STOLL R E STOLL and M STOLL 13 March 1974 [28 March 1973] 11129/74 Heading D1C In a flat knitting machine needle operating butts 14 are mounted on pivotal needle shanks 13 and may selectively occupy a projecting position as shown in Fig. 1, wherein they engage in cam tracks 30 and 30a in knitting and transfer locks 26 to 29 and 31 to 35 respectively, or a retracted position in the associated tricks 11 to which they are moved by the latching action e.g. of slides 19 engaging under a bar 21 in response to the selective advancement of jacks 15, such jacks having mounted in slots 152 therein for limited longitudinal displacement slides 23 with butts 22 which engage in a cam track 42 and are acted on at appropriate points by electromagnets 45 and permanent magnets 44 selectively to direct the butts into either runthrough branches 421 which leave the jacks 15 retracted and the needle butts 14 projecting or jack-advancing branches 422. The selection zones defined by the magnets on the passageway 42 correspond to significant phases of a knitting programme determined by the cam tracks 30, 30a viz. knitting or non-knitting, knitting or tucking, stitch transfer or non- transfer, stitch acceptance or non-acceptance and, in the case of a links-links machine, needle transfer or non-transfer and needleacceptance or non-acceptance. The jacks 15 are retracted by the engagement of butts 151 with restoring cams 36 to 41, of which the cams 36 and 38 are pivotable and spring loaded so as to be effective only in one direction of travel of the carriage. A jack advancing cam 46 moves all the jacks to the latching position at the end of the cam track 42. Depressions 291, 331 allow operating butts 14 to project from the tricks again after latching.

Patent GB-802289-A (GB)
Title: Improvements in control devices
IPC: F16H51/02
Filed: 1956-04-13
Abstract: 802,289. Cam mechanism. WANTZ, C. April 13, 1956 [Aug. 1, 1955], No. 11345/56. Class 80 (3). [Also in Group XXXVII] A control device, e.g. a switch for sequentially switching off the heater and motor of an electric clothes dryer, comprises a stationary cam with a helical surface engageable by a follower mounted on a shaft, the follower being adapted to make these movements relative to the cam under the control of a timing device: (1) a rotatable sliding movement, (2) an axial non- rotatable movement, (3) a further rotatable movement, and (4) a further axial non-rotatable movement. As shown, a plate 32 carrying bridging contacts 34, 36 is secured to a flexible plate 40 having slots 44 engaging fixed pins 42, thus allowing pivotal movement of the plate about the axis x-x. A sleeve 50 is slidable in the plate and normally has a shoulder 54 thereon pressed against the plate by springs 56, 58, one of which is fixed to the sleeve and the other of which is fixed to the plate. A shaft 46, slidable and rotatable in the sleeve, bears on a screw 52 carried by the sleeve, and carries a plate 88 having cam followers 90, 92 co-operating respectively with helical faces 102, 104 and 106, 108 on a fixed cam 94. Initially, the followers 90, 92 are in depressions 114 in the cam faces and are disengaged therefrom by depression of the shaft 46 by a knob 86. This causes the lever 32 to be pressed down against the action of a further spring 72 to bridge contacts 16, 18 and 24, 26 in the heater and motor circuits respectively. The knob is then rotated to move the followers 90, 92 along the helical faces 102, 106 to a desired extent, thereby depressing the shaft 46 and sleeve 50 relatively to the plate 32. This rotation winds up a clockwork mechanism 120 over a gear 122 and a pinion 124 which is connected to a spring 126 in turn connected at 130 to a spring 128 fixed to the plate 88. The angles of the faces 102, 104, 106, 108 are such that the axial pressure on shaft 46 of springs 56, 58 and 72 is insufficient to cause a rotary sliding movement of the followers relative to the cam faces. However, when the knob 86 is released, the clockwork rotates the shaft 46 back again until, when the followers 90, 92 are aligned with steps 110, 112 on the cam, the shoulder 54 is again in contact with the plate 32, so that as the followers 90, 92 drop down the steps, the shoulder 54 causes the plate 32 to pivot about the lower end of shaft 46 to open contacts 16, 18, 34. After further rotation of the shaft, the followers 90, 92 drop into depressions 114 and the plate 32 moves upwards until its left-hand end hits a stop 74 about which the plate then pivots to separate contacts 24, 26, 36.

Title: Improvements in or relating to facsimile telegraph systems
IPC: H04N1/00
Filed: 1940-07-09
Abstract: 542,700. Facsimile telegraphy. CREED & CO., Ltd., THOMPSON, A. E., and SALMON, R. D. July 9, 1940, No. 11428. [Class 40 (iii)] A facsimile telegraph transmitter for a message having matter in parallel lines comprises means for scanning each line in succession and means for shifting from one line to the next omitting the interlinear blanks. As shown, the message is wrapped round a drum 11, Fig. 5, and its edges are gripped by a longitudinal bar 12 urged inward by a spring 13. The drum 11 is splined on a square section shaft 14, Fig. 1, which is rotated by gearing 28, 29, from shaft 30 connected by further gearing to motor 23. The gear 29 can be adjusted around its shaft 30 and clamped thereto by a spring-loaded arm 32 adapted to engage holes or depressions in the side of the gear wheel. The drum lies between end plates 15 on a rack 16 in mesh with a pinion 17 geared by pinion 19 to a clutch member 20 adapted to be clutched to a shaft 21 geared to the motor 23. At every revolution of the drum, a mechanism driven thereby causes the clutch member 20 to be engaged by the shaft 21 and to drive the rack 16 to shift the drum one step along the shaft 14 to present successive lines of message matter to the scanning device. The scanning device comprises a lamp 36 having a straight filament, a lens system 37 for projecting a line of light on the message sheet on the drum parallel to the axis of the drum, a second lens system 38 for producing an image of that line on a slit in a screen 39, and a third lens system 40 for imaging the slit on a disc 41 provided with scanning holes and rotated by gearing from the motor 23. This scanning system is described in Specification 543,023. The motor 23 also drives through shaft 30, gearing 33, and pulley 34 a receiving tape 35 on which a received message is printed by means of a knife operated by an electromagnet on one side of the tape opposite a worm 44 on the other side. The worm is driven by the motor 23 and is inked by an inking roller. The worm has two turns ensuring recording even if receiver and transmitter are slightly out of phase.

Title: Electrical charge image storage apparatus
IPC: H01J29/10
Filed: 1966-03-17
Abstract: 1,102,395. Cathode-ray tubes. TEKTRONIX Inc. 17 March, 1966 [26 March, 1965], No. 11800/66. Heading H1D. In a direct-viewing bi-stable storage tube such as described in Specification 992,176 in which a combined storage and display target comprises an integral, porous layer of phosphor material through which secondary electrons generated by low velocity flood electrons are transmitted to a transparent, conductive backplate, the phosphor layer is also photo-sensitive and may comprise photo-emissive material such as magnesium oxide or photo-conductive material such as cadmium sulphide uniformly mixed with the phosphor material. The phosphor storage layer may be sensitive to an ultraviolet or to an X-ray image and may be used to store a light image of a graticule scale etched or printed on the inner surface of the tube face-plate beneath the transparent back-plate of the target. The face-plate may be first etched to form notches and the notches then filled with titanium dioxide. The graticule is illuminated by transmitting a flash of light through the outer edge of the face-plate. A separate light source is provided for ordinary illumination of the graticule. To store light images of low intensity the low velocity flood electrons are prevented from striking the target. The storage tube may be used to convert an X-ray image into a visible light image while simultaneously providing an electrical read-out signal. A low intensity light source may be employed to form a pointer spot on the storage layer which is not stored but does provide an electrical read-out signal. The storage target may be divided effectively in two, one area being operated in a storage mode and the other in a non-storage mode, e.g. for comparison or reference purposes. The same electron gun may be used for writing and reading operations and the tube comprises two flood guns. A light image may be projected on to the rear surface of the storage target through a window in the ceramic, funnel portion of the tube envelope. A light image may be projected by use of a point source of light or by use of laser beam or light may be reflected directly off a document. Switch positions of amplifiers and sweep generators may also be stored and reproduced.

Title: Improvements in and relating to reeling apparatus
Inventor: AXON PETER ERIC
IPC: G11B15/48
Filed: 1958-04-14
Abstract: 883,063. Magnetic recording and reproducing apparatus. BRITISH BROADCASTING CORPORATION. April 14, 1959 [April 14, 1958], No. 11819/58. Class 40 (2). [Also in Group XVI] In a magnetic tape reeling apparatus pressure rollers 22, 23 press the tape 10 into engagement with a capstan 21 only when the tape has reached a predetermined speed. While the machine is stopped the rollers 22, 23, mounted on arms 24, 25, are held apart by a cam 31. When the machine is switched on, the cam 31 is, by means not shown, slowly rotated clockwise, as viewed in Fig. 2, so that the rollers move the tape towards the capstan 21. During this period the take-up reel 12 is provided with a greater torque than in normal forward drive, and the supply reel 11 is given a forward torque instead of a small reverse torque. The cam-engaging members 26, 27 on the arms 24, 25, respectively, are so arranged that the tape is pressed into engagement with the capstan 21 by roller 23 in the first instance and then by the roller 22, at which point the drive of the cam 31 is broken by a microswitch (not shown) and a normal drive is established. A stopping operation restores the drive of the cam 31 which takes with it a cam 30 the constant radius parts of which spread the arms 24, 25 apart, at which point its rotation is again interrupted. In the event of a power failure the cam 30 may be manually operated to spread the arms 24, 25 apart by a handle 47. Arms 19, 20 are provided which rest on the outer turns of tape on the reels 11, 12, respectively, to control the amount of torque applied to the reels in accordance with the amount of tape on the reels.

Title: Electro-magnetic switches
IPC: H01H51/10
Filed: 1925-05-07
Abstract: 254,455. Railing, A. H., and Angold, A. E. May 7, 1925. Automatic circuitbreakers in which the contact - member is moved in two stages to the closed position by the joint action of a closing and a maintaining electromagnet have the contact arm 4 pivoted at 5 to a member 3 on a fixed pivot 2, the arm 4 being provided with a spring 11 for biassing it towards the off position, and the member 3 being released after the the setting position is reached so that it does not hamper the opening movement. Normally as shown the back of the arm 4 rests against a fixed stop 21 but when the closing electromagnet 8 is energized the attraction of its armature 7 which is carried by the member 3 moves the arm 4 to the intermediate position, the crossmember 6 carried by the member 3 engaging the rear portion of the contact-arm 4. In this position the pivoted armature 13 carried pivotally at 14 by the arm 4 is brought against the holding electromagnet 16 so that if this electromagnet is now energized and the closing electromagnet de-energized the spring 11 moves the parts to the closed position in which the movable contact 15 engages the fixed contact 1. In this position the arm 4 is free to be released immediately the switch closes if faulty conditions exist in the controlled circuit, as in the final closing movement the driving portion 6 of the member 3 has been moved away from the rear of the contact arm 4. To facilitate any movement which may occur between the armature 13 and the pole-piece of the holding electromagnet 16 during the final portion of the closing movement the co-operating surfaces of these members may be slightly rounded. The member 3 may be provided with an arm 17 connected by a link to the piston of a single or double-acting dash pot which may be provided with an adjustable relief valve.

Title: Method of preventing coarse crystallisation at the solidification of metallic castings
IPC: B22D27/20
Filed: 1933-04-24
Abstract: 405,842. Casting processes. VEREINIGTE STAHLWERKE AKT.-GES., 67, Breitestrasse, Dusseldorf, Germany. April 24, 1933, No. 11908. Convention date, May 2, 1932. [Class 83 (i).] To avoid coarse crystallisation in steel, zinc, or other metallic castings, solid material, isomorphous with the metal or alloy to be cast, is added thereto before or during pouring. The molten metal should be hot enough partly to melt the added material leaving a large number of unmelted crystal nuclei. The added solid may be some of the same metal or alloy as that to be cast or may be a slightly different alloy so as to melt at a higher temperature. The solid may be thrown into the ladle, or into the stream of metal or be placed or secured in the mould, for instance in the form of rods or wires which may be thinner adjacent the mould walls. The added solid may comprise from 0.1 to 5 per cent of the casting and may be coated to prevent corrosion or scale forming, for instance, a bar of nickel coated steel may be used.
Patent GB-418377-A (GB)
Title: A new or improved gyroscopic instrument for aircraft and the like
IPC: G01C19/44
Filed: 1933-04-24
Abstract: 418,377. Gyroscopic apparatus. DOVE, J. S., Hale House, Ockley, Surrey. April 24, 1933, Nos. 11924 and 34829. [Class 97 (iii).] In a gyroscopic instrument particularly for use in navigating aircraft, a rotor with three degrees of freedom is driven by and gyroscopically influenced by the airflow past the aircraft. In the form shown, the rotor comprises a rim 1 interconnecting massive balls 2 on spokes 3 radiating from a hub 4, which is mounted by ball bearings on an annular member 8. The latter is connected by a universal joint to a spindle 12, pivotally mounted in a U-shaped frame 13, which is pivoted at 14 to a supporting disc 16 and adjustable thereon by means of slot 17 and thumb nut 18. The lower part of the rotor: s shielded from the air stream by a screen 19 fixed to the frame 13. The air stream drives the rotor by impinging on the upper balls 2 and also causes a torque on the rotor precessing the latter into alignment with the air stream when it has become displaced by turning of the supporting aircraft. Yawing of the aircraft is indicated by movement of the rim 1 across the graduations 19A on the screen 19 and banking of the aircraft by tilting of the rim 1 relative to the lubber line 19B. Vanes 25 balanced by weights 26 are fixed on the member 8 and provide corrective or damping properties under the action of the air stream. The rotor may be centralized by moving a sleeve along the spindle 12 by links 22, 23, until a flange 21 engages a conical surface on the member 8. Fig. 3 shows the instrument applied as an automatic pilot. The weights 26 are replaced by a tail piece 31 connected by a link 32 and lever 33 to a bracket 34 adjustably fixed to a spindle 35 which is mounted in a bearing rigid with a spindle 37 and carries a vane 36 normally facing the wind. The spindle 37 is carried in a bearing in a lug 38 upstanding from a lever 39 pivoted at 40 and having an adjustable pin 42 engaging a slot 43 in a second lever 44, the spindle 45 of which is fixed to the rudder bar 46. An upstanding bearing 48 on the lever 44 supports a spindle 49 carrying a second servovane 50, normally parallel to the airstream and a pinion 51 geared to a pinion 52 which is connected by universal joints and extensible shaft 53 to the shaft 37. Upon yawing of the aircraft the tail 31 rocks the spindle 35 and gives the vane 36 an angle of incidence, whereupon the shaft 37 and pinion 52 are turned under the influence of the air stream on the vane. The pinion 52 gives an inclination to the second larger servo-vane 50, whereupon the lever 44 is rocked and the rudder bar 46 suitably operated. The pin and slot connection 42, 43 causes the lever 39 and first servo system to follow up the displacements of the rotor 30. A second tail 31 (not shown) may operate a servo system for controlling the ailerons. Three axis control may be obtained by using two rotors. The apparatus is arranged so that only the wind affected parts project from the outer surface 56 of the aircraft.
